Unit 3 & 4 test Review

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and replication. It ensures that our body’s cells grow and repair themselves.

Front

What amino acid is represented by the codon UUA?

Back

Leucine

Front

What is the longest stage of the cell cycle?

Back

Interphase, where the cell spends about 90% of its time.

Front

What does DNA hold the code for making?

Back

Proteins.

Front

What must be copied before cells can divide?

Back

DNA.

Front

What are the main phases of the cell cycle?

Back

The main phases are Interphase (G1, S, G2) and M phase (mitosis and cytokinesis).

Front

What occurs during the S phase of Interphase?

Back

DNA replication occurs, where the cell duplicates its DNA.

Front

What is cytokinesis?

Back

Cytokinesis is the process during cell division where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What is the role of proteins in the cell?

Back

Proteins perform a variety of functions including catalyzing metabolic reactions, replicating DNA, responding to stimuli, and transporting molecules.

Front

What is the function of mitochondria?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.
